Hack Correlation

This post is less of a guide and more of a collection of thoughts. It assumes some Java and camera operation knowledge. My S7 has become my main camera since it handles low-light, uploading, water and time zones very well. It does have a few big weakness though, oversharpening being one of them and over-confidence the other. By over-confidence I mean it will gladly lower the shutter speed to 1/4s, thinking OIS will take care of the shake. It can't. The Samsung camera app on Android Nougat has shed a lot of features in exchange of user-friendliness. Gone are the sharpness controls, OIS cannot be disabled, RAW mode is available only in the "Pro" camera mode. Quite a lot of artificial limitations which third-party apps don't seem to bring back. Start To analyze the application we need to take a look at some binaries: SamsungCamera6.apk, semcamera.jar and seccamera.jar. There are some other binaries but they are written in native C (libcamera_client.so) or ev...

In one of my most-viewed articles, from quite a few years ago, I've teared down a Saeco Talea Coffee machine and noticed a strange protrusion on top. I assumed it was an IrDa transceiver, then thought that maybe it was a coffee cup detector. It indeed turned out to be an infrared port. Armed with this knowledge - and some time to kill - I've decided to try and talk to the machine, wirelessly. While it might sound easy, there are many steps involved: get hold of the service tool application, reverse engineer (RE) it, RE the service dongle, RE the machine protocol, write an IrDa implementation for Arduino, write the web app to serve the page - and coffee. Step 1 - .NET reverse engineering Ever since I've discovered JetBrains' DotPeek, my life has been changed. I don't know C#, in fact I barely know C, but I can pretend to be a .NET developer. After getting hold of the SSC2 application (that's another topic in itself) we can try to see how it can ta...

I haven't had much time to write full articles but I can go through a quick rundown until I tackle each subject: CTC 3D Dual (Bizer) Printer Will create a separate article about the mods and results. I've re-tightened all the screws and tried to take out the backlash of the Z carrier. This has improved the jagged edges a bit and also reduced the noise. I made a small DIY enclosure: A4 plastic sheet on one side, the glass from a picture frame in the front, the particle wood panel from that frame in the other side. The glass frame was affixed with some 3D printed clamps as well as a modified Tic-Tac box. On the top of the printer I've cut some Ikea Schottis blinds (3$) that fold with the moving head. I found out afterwards that I'm not the first one to do this:  https://ultimaker.com/en/community/9484-umo-dust-cover I've cut a few pieces of 2.5-3mm glass to the bed dimensions. Rather, I've had a glass manufacturing company cut them for me (<10$). Th...
